7 and particularly to the end wipers of lasting mechanism of the bed type. In this type of lasting apparatus two or more wlper plates are butted together to present acting edges shaped to fit, for example, the toe end portion of the last which they are caused to embrace in their operation. The constant wear to which the wiper plates are subject tends to open up the abutting corners of these plates and it is often found that as the wipers or plates are moved relatively to the last to wipe the upper up the side faces of the last and are closed over the last bottom to lay the'upper over the margin of the innersole, the upper is forced into the crevice formed between these abutting cornersof the plates, thus forming a ridge or line on the toe of the shoe which must be eliminated after the shoe is removed from the machine.

An object of this invention is to provide a wiper that will wipe the upper up about the toe end of the last smoothly and without causing such a mark or ridge and with this end in view an important feature of the invention consists in a wiper havinga strictly uninterrupted or continuous acting edge.

A further feature of the invention resides in a wiper which presents an uninterrupted metallic acting edge to the toe of the shoe as the wipers are moved up the side faces of the last and closed to lay the upper over upon the last bottom.

The invention is herein shown as embodied in a set of wipers having an edge contour corresponding to the contour of the toe end of the last and provided on the acting face thereof with a continuous unyielding strip for engagement with the work.

These and other features of the invention, including certain details of. construction, will now be described in connection with the accompanying drawings and then pointed out in the claims.

I Figure 1 is a perspective of so much of the toe lasting mechanism as is required for illustrating this invention. Fig. 2 is a perspective of the wiper of the present invention.

The illustrated machine comprises the usual shoe supports and wiper carrying and actuating mechanism which in this instance is mounted for upward movementrelatively to the last, like that shown and described in United States Letters Patent No. 552,834, granted January 7, 1896, on application of Edward F. Grandy. The toe wipers comprise the plates 2 and 4 shaped to the contour of the toe and arranged so that the inner corner of one of the plates is abutted against the corresponding corner of the other plate. These plates are slotted for connection by clamps 5 with the wiper actuating cams 6, the cams 6 being cut away at their under sides to form seats to cooperate with the clamps to hold-the plates rigidly in place. In the illustrated embodiment of the invention the inner edges of the plates 2 and 4 are provided with a groove in which is seated a resilient strip of spring metal 8, preferably round in cross section,at least on its face which is to engage the work. The

grooves in the plates are of sufficient depth to allow only a small portion of the wire to project beyond their edges. The strip is confined in place at each end to the plates 2 and 4 by the clips 9 and screws 12 and the resilient nature of the strip causes it to remain securely in place in the plates while the plates are opened and closed.

It will be seen from the foregoing description that as the wipers are moved upwardly along the side faces of the shoe which is held against upward movement by the holddown 13 they present a strictly unbroken and rigid metallic acting edge to stretch and conform the upper smoothly to the shape of the last, the strip 8 preventing the upper from wedging in between the butted corners of the plates.

Having fully described my invention What I claim as new and desire to secure by Letters Patent of the United States is 1. In a lasting machine end embracing wipers comprising a plurality of plates having grooves in the inner edge face thereof, and'a strip of resilient metal retained in said grooves and forming a continuous acting edge face for said end embracing wipers.

7 2. In a'lasting mechanism end embracing wipers comprising a plurality of individually rigid plates, and means located wholly end portions of said resilient means to the plates.

L In a lasting machine, the combination with relatively movable lasting plates having edges shaped to embrace the toe of the last and arranged to wipe the upper up the sides and end of a shoe toe and over the feather of a sole, of a member presenting a continuous acting edge for said plates around thetoe,the plates being constructed and ar ranged to retain said member against verti 'Ciil displacement relatively thereto.

5. In a lasting mechanism end embracing wipers comprising a pair of cooperating plates having formed in their inner edges a groove which also extends along their ends, a U shaped resilient strip having its ends outturned and fitting said groove to bridge the joint between. the plates and form an uninterrupted edge face for their engagement with the work, and clips'for confining the outturned ends of the strip to the ends of the plates.

6; In a lasting machine, endembracing Wipers comprising a plurality of abutting plates having their work engaging edges shaped to embrace the toe of a shoe, and upper engaging means carried by the plates and extending across the junction of the abutting faces of the plates to form an uninterrupted working edge face for said plates, said plates being constructed and arranged to hold the upper engaging means from movement relatively to the plates by contact with the sidesof the shoe toe when the plates areinoved' vertically in either direction.

' 7. In an end lasting machine, end embracing wipers, and a member bridging the oint between the wipers, one of saidparts having a groove and the other being shaped to fit into the groove for holding them from relative vertical displacement during use.

8. In an end lasting machine, end embracing wipers, and a resilient edge member constructed and arranged to bridge the joint between the wipers, and means on the wipers embracing the ends of said member.

In testimony whereof I have signed my name to. this specification in the presence of two subscribing witnesses.
